SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
(1)A Supplemental Restraint System (SRS), which uses a driver-side air bag, has been installed in the 3668GT.(2)The SRS includes the following components: impact sensors, SRS diagnosis unit: SRS warning light, air bagmodule, clock spring, interconnecting wiring. Other SRS-related components (that may have to beremoved/installed in connection with SRS service or maintenance) are indicated in the table of contents byan asterisk (*).
WARNING!(1)Improper service or maintenance of any component of the SRS, or any SRS-related component, can lead topersonal injury or death to service personnel (from inadvertent firing of the air bag) or to the driver (from
rendering the SRS inoperative).
(2) Service or maintenance of any SRS component or SRS-related component must be performed only at an
authorized MITSUBISHI dealer.
(3) MlTSUBISHI dealer personnel must thoroughly review this manual, and especially its GROUP 52B -Supplemental Restraint System (SRS), before beginning any service or maintenance of any component of the

OBTAINING FAULT CODES(1) Connect the voltmeter or multi-use tester to the connector
for diagnosis.
(2) Read the output fault codes.
Then follow the remedy procedures according to the
“FAULT CODE DESCRIPTION” on the following page.
NOTEl As many as a maximum of ten fault codes, in the
sequence of occurrence, can be stored in the Random
Access Memory (RAM) incorporated within the control
unit.
l If the number of stored fault codes or fault patterns
exceeds ten, already stored fault codes will be erased,
in sequence beginning with the oldest.
l Do not disconnect the battery until all fault codes or
fault patterns have been read out, because all stored
fault codes or fault patterns will be canceled when the
battery is disconnected.
(3) If the fail-safe system is activated and the transaxle is
locked in 3rd gear, the fault code in the Fail-Safe Code
Description will be stored in the RAM.
Three of these fault codes can be stored.
(4) The cancellation will occur if, with the transaxle locked in
3rd gear, the ignition key is turned to the OFF position, but
the fault code is stored in the RAM.
